Term (Index) Definition
wide bandgap semiconductor  semiconductor featuring energy gap Eg > 2.5 eV (rather arbitrary criterion), useful in high temperature applications and emission of blue radiation (should feature direct bandgap at the same time); e.g. SiC (Eg = 2.9 eV), GaN (Eg = 3.5 eV), ZnS (Eg = 3.68 eV)
gallium nitride, GaN  wide bandgap III-V semiconductor featuring direct bandgap 3.5 eV wide; among very few semiconductors capable of generating blue radiation; number one candidate for blue LEDs and lasers; see "GaN note" on www.semiconductornotes.com for more information.

Reference: See Semiconductor Notes for more information on GaN
silicon carbide, SiC  semiconductor featuring energy gap Eg = 2.9 -3.05 eV (wide bandgap semiconductor), indirect bandgap; SiC can be obtained in several polytypes- most common hexagonal in the form of either 4H or 6H polytypes; parameters vary depending on polytype; higher than Si and GaAs electron saturation velocity; carrier mobility: electrons 100-500 cm2/Vs, holes 20 cm2/Vs; thermal conductivity 3 W/cmK (two times higher than Si); excellent semiconductor, however, difficult and expensive to fabricate in the form of single-crystal wafers; best suited for high power, high temperature devices; also limited use in photonic devices (e.g. substrate for GaN).

Reference: SemiOneSource,Notes
Zinc sulfide, ZnS  II-VI semiconductor, has a largest bandgap among semiconductors considered for practical applications (Eg = 3.68 eV) which in conjunctions with a bandgap being direct makes ZnS potentially attractive as a blue light emitter.
diamond  single-crystal carbon; material featuring outstanding semiconductor properties; wide bandgap semiconductor; in theory the best semiconductor, in practice very difficult to form in shapes and quantities compatible with manufacturing of semiconductor devices; also, restrictions on p-n junction formation due to the lack of adequate dopants.
